Advanced Imaging Technologies in Ophthalmology: Optical Coherence Tomography, Angiography, and Beyond

This chapter examines the technical principles and clinical applications of next-generation retinal and anterior segment imaging technologies, including swept-source optical coherence tomography, OCT angiography, adaptive optics, and wide-field fundus imaging. It discusses how these modalities have redefined the understanding of ocular disease pathophysiology, enhanced early detection, and guided treatment monitoring across a spectrum of conditions, while addressing ongoing limitations and future directions in multimodal imaging integration.
